Radiation harassment testing, what is it?

Radiation harassment mainly refers to the phenomenon where energy is emitted from a source to space in the form of electromagnetic waves or energy propagates in space in the form of electromagnetic waves. Radiation harassment is an important aspect of electromagnetic compatibility and is a project that is difficult to pass testing and rectify. Products with excessive radiation harassment may cause a decrease in the performance of surrounding devices, equipment, or systems, disrupt the normal operation of information technology equipment or other electronic products, and pose certain risks to human health.


Content of radiation harassment testing:

The EUT is placed at the specified height on the ground and arranged to simulate normal operation. The antenna is placed at the prescribed distance. The EUT is rotated within the horizontal plane, and the maximum reading is recorded. Then, adjust the antenna height to bring the direct wave and ground-reflected wave close to or achieve in-phase superposition to identify the maximum harassment value.


Measurement distance:

Refers to the distance between the point on the EUT closest to the antenna and the center of the antenna's projection on the ground. The 10-meter method is preferred, with the option of the 3-meter method.


Antenna height:

The height of the antenna above the ground should vary within the specified range to obtain the maximum reading that occurs when the direct wave and reflected wave are in phase. For measurement distances ≤10 meters, the antenna height is preferably varied between 1 meter and 4 meters.


Frequency range:

New standards require measurements from 30MHz to 6GHz.


Detection technology:

JJRLAB laboratory space radiation uses imported testing equipment from R&S and Schwarzbeck, which is a fully electrically shielded chamber designed for desktop EUT testing applicable at a 3m test distance. It has excellent normalized site attenuation characteristics (±3.5dB) from 30MHz to 1GHz and complies with the requirements of CISPR 16-1-4 for site voltage standing wave ratio (5.5dB) from 1GHz to 18GHz. The standard configuration of the chamber includes antenna towers and turntables with scanning heights of 1-4 meters and their controllers. It presents an innovative concept with its availability, customizability, and executability, thus achieving efficient and economical solutions.
